JOHN ROTH, OF GRANITE CITY, ILLINOIS.

STOVEPIP E-ANCI-IOR.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed February 9, 1914. Serial No. 817,591.

To all whom it may concern:

Be it known that I, JOHN ROTH, citizen of the United States, residing at Granite City, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Stovepipe-Anchors, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in stove-pipe anchors; and it consists in the novel details of construction more fully set forth in the specification and pointed out in the claim.

In the drawings, Figure 1 is a side elevation of a stove-pipe section showing my invention applied thereto, the flue into which the pipe discharges being shown in section, and parts of the pipe being broken away; Fig. 2 is an enlarged side elevation of the stove-pipe, with parts broken away, showing the application of my invention; Fig. 3 is an end view of the pipe with my anchor in position; and Fig. at is a perspective of the anchor detached.

The present invention is specifically .directed to devices for anchoring stove-pipes to the walls of the opening leading to the smoke fine, and has for its object to construct an anchor which can be readily applied to the section of pipe to be anchored; one which will conform to any size opening within certain limits; one which is simple, cheap, and durable, and one possessing further and other advantages better apparent from a detailed description of the invention which is as follows:

Referring to the drawings, P represents a conventional pipe-section whose discharge end is inserted into the opening 0 leading to the flue passage F, said opening being provided with a lining L as well understood in the art. The pipe terminal adjacent the opening 0 is provided with a peripheral bead or groove a which performs a special function in connection with my improved anchor. The anchor proper comprises a circular band or ring 1, provided at intervals with resilient cross-bars or strips 2 disposed parallel to the axis of the pipe and of the ring, the inner ends of said strips terminating in outwardly deflected lugs 0r lips 3 adapted to engage the walls of the groove (4, the resiliency of the strips causing the lips 3 to frictionally bear against the walls of the groove and thus causing the anchor to retain its position in the pipe. The outer portions of the members 2 are provided with outwardly bent portions or offsets 4, from which extend the outer terminal fingers or extensions 5. In their normal and released position the members 2 with their terminal fingers 5 are substan tially parallel to the walls of the pipe; but when the end of the latter is inserted into the opening 0, the members 2 and arms 5 thereof are sprung inwardly, to a degree depending on the size or cross-sectional diameter of the opening (see dotted position Fig. 2, and full showing in Fig. 1). When sprung to enter an opening 0 of normal size, the engagement of the arms or gripping fingers 5 with the walls of the lining L is at a point near the bases of the fingers; as the opening becomes larger, the spring of the arms becomes less defined, and the engagement is extended over a larger port-ion of the outer surfaces of the arms as clearly obvious from the drawings.

In the example here shown I provide two strips 2 at points diametrically opposite one another but it is obvious that I may vary this number should it become desirable. The groove a is so positioned, and the strips 2 are of proper length so that when the ring 1 is inserted into the pipe to a point to cause the lips 3 to engage the groove walls, the offsets 4 will be on the outside of the pipe, making it possible to seize the fingers 0r grippers 5 and deflect them inwardly in the act of insertion of the pipe into the opening 0.

The device may be used as quite obvious from the drawings, for coupling two sections of pipe together, one section carrying the ring or band 1 and the other being gripped by the fingers 5.

Having described my invention what I claim is In combination with a chimney fine and opening leading thereinto, stove-pipe having a peripheral groove beaded at a point near the discharge end of the pipe, an ancho r comprising a. ring insertibl into the pipe between said groove and the end of the pipe, resilient cross-bars secured to the ring and disposed parallel to the axis thereof, the inner terminaisofthe burs beengage the Walls, of the opening of the flue ing provided with outwardly turned lips intowhich the pipe discharges. 1') engaging the groove aforesaid,suitable out- In testimony whereof I affix my signawardly direct-ed ofisets formed on the hairs ture, in presence of two Witnesses.

at points outside of and contiguous to, the JOHN ROTH. ends of the pipe, and extension fingers lead- Witnesses:
